Alternate or pronated? What's safest and most effective?
Hey Cap,
Are you dead lifting for power or physique?
Alt. grip will give more power, but a lot of bodybuilders who DL more for reps use a double pronated (over) grip for more equal distribution of stress on the back.
And yeah, this grip will reduce most people's max. But again, what's your goal?
As for the bi tear, make sure you keep your arms straight!
I don't know if this is what caused your tear, but...
I've seen many a lifter shrugging or dead lifting with their arms bent at the elbow (anywhere from 4-6 degrees in some instances).
Okay with light weight, but as you go heavier, elbow flexion during these lifts DOES put stress on the biceps.
So be careful.
